DANBURY -- Police say a 23-year-old Bridgeport man was shot and killed on White Street early Saturday following a fight at an Elm Street nightclub.

Police have not yet released the name of the victim, who was found at about 2 a.m. on the sidewalk adjoining a parking lot for the shopping plaza at 301 Main Street.

Authorities believe the shooting was connected to a fight a short time earlier at Mambo Cafe, and investigators are reviewing security videos from the club they hope will help them identify the gunman, police said.

The cafe was closed on Sunday.

"Obviously, it's a very tragic situation," said Mayor Mark Boughton, "and our prayers go out to the family."

Boughton called the shooting -- the first homicide in the city in 2014 but the third in the past nine months -- "an isolated incident in a very safe community."

According to a law enforcement source and others familiar with the investigation, police responded to a fight at the cafe just before 2 a.m., near closing time for clubs in the downtown entertainment district. Extra police officers are on duty at that time, to handle the crowds.

That's when the shooting occurred, barely a block away, sources said.

Detective Capt. Mitchell Weston said in a release issued Saturday that the fight involved a large number of people. But police did not provide other information, including how many times the victim had been shot.

EMS transported the victim to Danbury Hospital where he later died, according to police.

Owners of several businesses on White Street said police contacted them Sunday morning and asked whether any had security cameras that might have captured images of the homicide, but none were able to provide investigators with the requested footage.

The homicide was the third in Danbury since last September, when 25-year-old Christian Williams was charged with manslaughter in the death of his 19-month-old son. Emanuel Von Harris, 17, was later charged with murder in the Dec. 12 stabbing of Luan Pitol during a fight between two groups of young people on West Wooster Street.

The accused in those cases have pleaded not guilty, and their cases are pending in state Superior Court in Danbury.

Police are asking anyone with information about the White Street shooting to call detectives at 203-797-4662.
